The high-speed thermometer adopts a precision optical system and imported photoelectric sensors. The temperature measurement range of the instrument is wide, and it can meet the different needs of users within the range of -25°C to 1500°C. It is aimed at the coaxial laser, which can accurately measure the temperature of the target, with stable repeat measurement, fast response, simple operation and reliable use.

High-speed thermometers are widely used in process control and equipment fault diagnosis in forging, induction heating, heat treatment, electric power and other industries, as well as energy-saving industries and scientific research.
The high-speed thermometer can measure the temperature of the object behind the glass through the glass, and it is very accurate. It depends on several things:
1. The glass must be inorganic glass, and the wavelength of the instrument must be a short wavelength. At this time, the measured temperature is very accurate;
2. The glass is inorganic glass, but when the wavelength of the instrument is long-wave or medium-wave, it is necessary to use infrared glass that can pass through long-wave or medium-wave, such as zinc selenide glass, calcium fluoride glass, and zinc sulfide glass; at this time, according to infrared The transmittance of the glass is used to adjust the emissivity accordingly to ensure the temperature measurement accuracy;
3. When the glass is plexiglass, it is necessary to ensure that the plexiglass is clean and free of scratches to ensure the temperature measurement accuracy, and the emissivity needs to be adjusted at a certain time. In fact, this instrument can not only measure temperature through glass, but also through flame, but it needs to use a special wavelength of 3.9 microns.
